I am Moldavian, will travel to India soon! posible to get visa from New Delhi to china for 6 months?

Unless you have valid Indian visa or valid Residence Permit in India and its copy. If you are there with a short-term one, a note verbale (with details as follows: your name, passport number, occupation, purpose to go to China, duration of stay) by the Embassy or Consulate-General of Moldavia is required. So, if possible, you are suggested to apply in advance.
